To all whom it may conceive: a I

Be itknown that I, Gnovsn Groooinoii area of avalvh seat for the passage of .fi11il and produce a plate valve 'which is'simple in construction, and not liable to break.

.Other objects of the invention are to enable plate valves in the form of curvedor se inental strips of sheet 'metal to be properly guided as the plates move to and from their seats without e'ncessivewear and rubhing, and insure the seating of the plates in substantially the same places eachtime they return to their seats.

Further objects will hereinafter appear and to all of these ends the invention eonsists in the features of construction and combinations of elements herein described and claimed and shown in its preferred forms ip the accompanying drawings, in whichv Figure 1 is a transverse sectional view of a valve on the line 11 of Fig. 4;

2 is a perspective view in transverse section of the valve seat;

3 Fig. 3 is a perspective view of a series of valve plates adapted to be seated on the valve seat;

Figs. 4 and 5 together show a plan view of the stop plate and valve plate broken away through the center, the left hand half (Fig. 5) being a top plan and the right hand half (Fig. 4) being a bottom plan, with the valve plates in dot and dash lines to indicate their positions in the guiding recesses of the stop plate;

Figs. fiend '7 are detail sectional views of modifications.

Referring to the drawings, 'A represents a valve seat of usual form having concentrically arranged passageways B which may be separated by the radial Webs or :idges C. In accordance with this invention, the valve plates D adapted to he seat.-

\l over the oassaaewavs B are in thefoam- Specificatio: of Letters Patent. HPat entd May 3 1921 Application filed Apri1.6,

of separate disconnected fl'ahcurved or segmental strips of sheet metal, conforming to the curvatute'of the passageways B on the face of the valve seatv A stop plate or guard ll 'adapted to be mounted onthe valve A'over the valve plates as indicated in Fig. l, and the stop plate .E ispreferab y formed with the arms F having recesses or sockets G for" the re ception' of valve springs H which are referably in the form of coiledlspi ings. valve springs H may, "if desired, 'bear directly on the valveplates '1) as shown in Fig, Land in thistorin of the invention means are prov ded for guiding the valve plates andv for hnutm both transverse and endwise movement ot the valve plates as;

"they move to and from their seats.- One suitable means for guiding the'ends of the valve platesis shown in FigszQ, land 5 lib elusive, and consists of guldepms inserted 1n the upper face oi the valve seat A.

and locatedbetween the-arms F of the stop plate E at the ends oi' the passagewayslg,

but I do not limit myself "to guide pins as other forms of guiding means may be devised,in fact, I have shown other forms in the modifications indicated in Figs. 6 and. 7 to be described.

in order to-prpvideguiding means for the valve' plates in transverse or radial direc-. tionsre latlvely to the valve seat A, the stop plate arms F are provided with guide recesses K, underneath thespring receiving.

apertures G". Within. the guide recesses, the valve plates are adapted to lift, and the guide pins J and the sides of the guide recesses effectually serve to guide the valve plates.

In assembling the parts a dowelpin L is preferably provided between the valve seat A and the stop plate E to position the-parts,

and the usual bolt 0 is provided for securing the parts together. I

In the modifications or" the invention shown in Fig. 6, the guide recesses K are omitted from the stop plate Ff and the valve plates D are suitably secured to guide sh es P as by means of the rivets Q. These :guide shoesfll are provided with reduced portions or centering-lugs It over which the springslH are adapted to lie, and if desired,

the springs may be suitably connected to the phoes P or to the lugs It in any suitable manand the stop net. The shoes P are further provided with. the guiding and centering pins S extending through the springs and through apertures in the -stop plate E-. The shoes P guided in thespring apertures or sockets G and serve to guide .the movementof the valve plates D. In this form of the invention any wear ziomes between the guide shoes ate.

In theme ification shown in Fig. 7, the valve plates 1) are suitably welded or otherwise secured to the guide shoes T in theform of thimbles extending over the sprin s H in the spring receiving recesses or socllets G. Any wear during the lift of the valve comes between the thimbles and the stofa plate E. claim:

1. A. plate valve comprising a valve seat having concentrically arranged passage-- ways inthe same plane, valve plates in the form of separate segmental strips adapted to be Seated over said passageways,a stop plate mounted on the valve seat over the valve plates, springs for seating said valve plates, and means for guiding said valve plates.

2. A plate valve comprising a valve seat having concentrically arranged passageways ix 1-:the same plane, valve plates in the form pf separate disconneeted segmental strips adapted to be seated over said. passageway s a stop pla ts mounted on the valve seat ever the valve plates, springs for seating said valve plates, and means for limiting both transverse and endvvise movement of the valve plates as they move to and from their seats.

3, A plate valve comprising a valve seat having "concentrically arranged passage Ways in the same plane, valve plates in the foim of separate segmental strips adapted to be seated over said passageways, a stop plate mounted on the valve seat over the valve plates, saiil stop plate being provided. with recesses, springs in recesses over the valve plates, ani'l means oo'tig ievating -with the springs for guiding the valve they move to fiilii from th. v seats plate ilve comprising a valve seat having concentyicall y arranged passage Ways in the same plane, valve plates in the form of separate segmental strips adapted to be seated over said passageways, a stop plate mounted on the valve seat eve valve plates, springs for seating said valve plates, shoes connected to the valve plates beneath the springs, and means "for guiding the shoes valve plates move to and from their seats In testimony whereof I have hereunto set i my hand
